BONSDA's metal dome arrays represent the evolution of tactile switch technology. These are not individual components but complete pre-assembled switch panels where multiple metal domes (3-12mm sizes) are factory-mounted on custom-designed PET films according to your specific PCB layout.
Each array features precisely positioned domes in round, cross, or oblong shapes with customizable actuation forces (80-2500gf) and lifespans (30K-5M cycles). The sophisticated PET film construction includes a 0.045mm cover layer and 0.07mm spacer layer with micro-ventilation channels to prevent air entrapment during operation.
Our engineering process ensures perfect PCB alignment through multi-layer PET architecture with specialized features:
Micro-air vents for reliable tactile response
3M or Avery FC440 adhesive options for extreme environments
Temperature resistance from -30℃ to +70℃
Mechanical durability tested to 500,000 cycles
These turnkey solutions eliminate manual placement errors while providing consistent tactile feedback across all domes. Applications span industrial HMIs, automotive interfaces, medical equipment, and smart home panels where reliability and precision matter most.
BONSDA supports complete customization from prototype to production, offering domestic PET films or premium imported adhesives. Each array undergoes rigorous testing including thermal cycling, humidity resistance, and mechanical endurance validation.
The result? A switch solution that delivers 10x longer lifespan than traditional membrane switches while simplifying your supply chain with ready-to-install modules. From the basic dome specifications to advanced PET film engineering, BONSDA metal dome arrays bridge the gap between component manufacturing and complete switch system integration.
